    The invention relates to chemical current sources and relates to an electrolyte salt used in a liquid cathode depolarizer. Electrolytic salts must satisfy several criteria. Some criteria include the high ionic strength or electrical conductivity of the salt for transporting the elements in the element discharge. The electrolyte salts 10 must also be well soluble in the housing depolarizer — an electrolyte solvent, and stable with respect to the liquid depolarizer, the electrolyte solvent, and the anode metal 15.
    A chemical current source is known, containing an alkaline or alkaline-earth anode, a liquid cathode depole. It is a radiator with tetrachloroaluminate S dissolved in the electrolyte tetrachloroalkane dissolved in it.
    However, at low speed, the discharge energy intensity of such a current source decreases .25
    The closest to the proposed: the technical essence and the achieved result is the 1st primary current source containing an alkaline or alkaline earth liquid cathode) 1st depolarizer and electrolyte. Add salt from tetrachloro and tetrachloride dissolved in it 2j.
    However, the capacity of such a current source is also insufficient.
    The purpose of the invention is to increase the energy intensity of the current source.
    For this purpose, an alkali or alkaline earth metal tetrahalohalide is taken as the electrolyte salt in the current source.
    Liquid hydroxy halides, nonmetals oxides, nonmetals halides and their mixtures, such as oxychlorophosphorus POC C, selenium oxychloride Se O1, sulfur dioxide SO 2, sulfur trioxide SOj, vanadium oxytrichloride VOCI%, chromylchloride 393683, sulfuryl chloride, nitrile chloride, nitrosylchporide (NOC), nitrogen dioxide N0., sulfur monochloride S, and sulfur monobromide S-Br. electrolyte solvent or to each separately. Example I. Li Pa Od is prepared by mixing equimolar amounts of Ga CI and Li CU melts. A single molar solution of Li Ga C1 SO Ga Cl is readily dissolved in So Cl) and the ionic conductivity is determined. At room temperature, it is 1, 13 IO Ω-cm. This is in good agreement with the electrical conductivity of a 1 M solution of Li A1 CPS So Cl, which is 1.6. Thus, the electrical conductivity, Li Ga C C, is suitable for Li / SoCl Element, which has a high discharge rate.
    P r i m e. Brilliant lithium | yulgi pieces are added to the LI Ga CK-So C1 solution of Example 1 and boiled under reflux for 8 days at 85 ° C. At the end of the boiling process, the lithium cells are bright and shiny, indicating that Li Ga SC So Cl is chemically compatible with lithium and therefore can be used as an electrolyte in a lithium anode cell. The absence of color change and / or corrosion indicates that a protective coating of sufficient but minimal thickness is formed on the lithium surface; I like something grained coating, corrosion and lack of coverage ..
    At measure 3. Several elements with a diameter of 33 mm and a length of 60.5 mm are made by winding a lithium anode, having dimensions of 540 mm 50 mm 0.38 mm, with a carbon cathode on flared metallic nickel having dimensions of 510 mm 45 mm t 0, 65 MMK and a two-layer separator - sheets of fiberglass. Each of the elements is filled with 45 g of a molar L1 Ga So C solution prepared in accordance with Examples 1 and 2. The elements are discharged at different currents.
    The results are shown in Table. one.
    Example 5. In table. 3 shows the comparative characteristics of the proposed current source with the known.
